I'd try to first downgrade to 7.0, copy the 6.3 code as file on flash 
while running 7.0, and then use the "downgrade" command.

Just out of precaution - make a note of your current activation key. And 
depending on whether you activated the features that were not in 6.3, you 
might need a new key.

Yes, 6.3 formats the flash differently - it uses a much simpler filesystem 
than in 7.x+

When you downgrade, the flash will be reformatted, so the ASDM image as 
you see it now won't be there anymore.
